This section describes the frontpanel functionality of the Shapeshifter. It also serves as a decent overview of the synthesis options available.
After pressing a panel button, in most cases turn the left data encoder to change the value of the displayed parameter.
Note: Preset mode is covered in it's own section.
|Frontpanel: Top Left|
|WAVE BANK||Press to edit the wavetable bank for OSC1. Press again to edit the wavetable bank for OSC2.|
|SYNC / PULSE||Press one or more times to edit (in order) OSC1 sync, OSC2 sync, Pulse output mode. See the additional sections for description of sync and pulse modes.|
|MOD A||Press to edit the modulation destination for MODA input. Press again to edit whether OSC2 output modifies SHAPE1, TILT, or nothing.|
|MULTI / CHORD TYPE||
The MULTI setting for each oscillator joins subsequent waveforms from the wavetable into a single waveform. For example when MULTI for OSC 1 is set to 2, OSC 1 will emit one cycle of the current waveform, then one cycle of the next waveform in the wavetable, then back to one cycle of the first waveform, etc.
Press MULTI to edit OSC1 multi. Press again to edit OSC2 multi. If CHORD MODE is activated, press a third time to edit CHORD TYPE. See "Chord Types" section for a description of all chord types available.
|Frontpanel: Top Right|
Press to change the mode how OSC1 and OSC2 are combined before being sent to OUT1.
Press a second time to enable MOD B control over COMBO MODE. See "Combo Modes" sections for description of each combo mode.
|TILT / CHORD DRIVE||
TILT phase modulates OSC 1 with it's own output, effectively "tilting" the waveform.
Press to modify the TILT level for OSC 1. Press a second time to enable MOD B control over TILT.
When CHORD MODE is active, this button edits CHORD DRIVE instead of TILT. CHORD DRIVE amplifies, then clips, each voice in the chord.
OUT1 is optionally run through a delay line whose delay time is equal to OSC2 frequency.
Press to edit delay depth, which sets both the amount of delay feedback and the wet/dry output ratio. Press again to enable MOD B modulation of DELAY DEPTH.
Set OSC2 to LFO mode for a traditional delay effect, or set it to audio rate for the delay line to act as a resonator.
|CHORD DETUNE / PERC DECAY||
If CHORD MODE is enabled, press to edit CHORD DETUNE, which fattens the chord sound by detuning each oscillator. Press a second time to enable MOD B modulation of CHORD DETUNE.
If PERCUSSION MODE is enabled, the percussion envelope decay time (PERC DELAY) will be edited when this button is pressed instead. Press a second time to enable MOD B modulation of PERC DELAY.
|Frontpanel: Middle Section|
|QUANT and RATIO/TIME||
When QUANT is disabled, OSC 2's frequency is controlled by PITCH 2, offset by RATIO.
When QUANT is enabled, PITCH 2 input is ignored and OSC 2's frequency is a fixed fraction or multiple ratio OSC 1's frequency, controlled by RATIO. The possible frequency ratios for OSC 2 are 1/8, 3/16, 1/4, 5/16, 3/8, 1/2, 5/8, 3/4, 1, 5/4, 3/2, 2, 3, 4, 6, 8.
When QUANT is flashing, OSC 2's frequency is clocked to an incoming clock signal present on the PITCH 2 input. RATIO controls a clock divider / multiplier with possible ratios of 1/24, 1/16, 1/12, 1/8, 1/6, 1/4, 1/3, 1/2, 1, 2, 3, 4, 6, 8, 12. In this case, the LFO2 setting is ignored.
|INT FM||This knob, combined with the INT. FM CV input, controls how much OSC 2's output modulates OSC 1's frequency.|
When lit, both OSC 1 and OSC 2 are synced to an internal oscillator running at the same base frequency as OSC 1 (but not affected by OSC 1 FM inputs).
When flashing, the internal oscillator is set to half of OSC 1's frequency.
See "Sync Modes" to understand how OSC 1 and OSC 2 will react to sync.
|COARSE / FINE||These provide an offset to both OSC 1 and OSC 2 frequency.|
|LFO / 1 / 2||
Press to cycle through setting OSC 2, OSC 1, or both to LFO speeds, lowered by 7 octaves.
When LFO 2 is enabled and QUANT is disabled, OSC 2's frequency is no longer affected by COARSE and FINE knobs.
When enabled, OSC1 emits 8-oscillator chords, controlled by CHORD TYPE and CHORD DETUNE.
Some other frontpanel buttons change functionality with CHORD MODE enabled.
|SHAPE 1 / SHAPE 2||SHAPE 1 and SHAPE 2 (combined with their respective CV inputs) choose a smoothly interpolated waveform for OSC 1 and OSC 2 from their currently selected wave banks.|
When PERCUSSION MODE enabled, an envelope controls the gain of OUT 1. The envelope decay time is controlled by the PERC DECAY parameter.
Press PERC MODE once to enable PERCUSSION MODE, where the decay envelope is triggered by a rising edge on the SYNC input.
Press PERC MODE a second time and the decay envelope will remain high as long as SYNC input is high.
|FOLD||FOLD knob plus FOLD CV input controls the depth of the analog wavefolding applied to the FOLD input (which is normaled to OUT 1).|
|Frontpanel: Modulation Row|
|RATIO||Combines with RATIO knob. See QUANT / RATIO above.|
|INT. FM||Combines with INT. FM knob to determine the depth of internal frequency modulation.|
|FM 1||Modulates OSC 1 frequency.|
|FOLD CV||Combines with FOLD knob to determine depth of wavefolding applied to FOLD input.|
|MOD A||AC-coupled input to the MOD A modulation bus. Note that it is normaled to OUT 1, so even with nothing plugged in the MOD A attenuator controls the depth of modulation and a signal is present.|
|SHAPE 1 / SHAPE 2||Combines with SHAPE 1 / SHAPE 2 knobs to calculate OSC 1 and OSC 2 positions within their active wavetable banks.|
|MOD B||Combines with MOD B knob to determine the value of the MOD B modulation bus.|
|Frontpanel: Bottom Row|
|PEAK / LFO 1||
When OSC 1 is not in LFO mode, this LED indicates either FM 1 or MOD A inputs are hitting the limits of their ranges and are clipping.
When OSC 1 is in LFO mode, this LED is lit when OSC 1's polarity is positive.
|PITCH 1 / PITCH 2||1V/oct voltage inputs for OSC 1 and OSC 2. PITCH 2 is normalled to PITCH 1. When QUANT mode is flashing, PITCH 2 expects a clock signal to sync to instead of a V/oct signal.|
Rising edges on this input will cause OSC 1 and OSC 2 to sync based on their active SYNC modes.
When PERC mode is activated this input controls the percussion envelope.
|FOLD IN||Input to the onboard analog wavefolder, normalled to OUT 1.|
|OUT 1||Output 1, which is the result of OSC 1 optionally combined with OSC 2, optionally through the percussion mode envelope, then optionally through the delay line.|
|OUT 2||Oscillator 2 output.|
|Pulse||Configurable pulse (0-5v) output controlled by PULSE setting.|
|FOLD||Output of the analog wavefolder.|
|PULSE / LFO 2||
When OSC 2 is not in LFO mode, this LED indicates when the PULSE output is high.
When OSC 2 is in LFO mode, this LED indicates when OSC 2 polarity is positive.
To change combo modes press COMBO MODE and rotate the data encoder.
Press COMBO MODE twice to modulate combo mode via MOD B.
|osc1||OUT1 is the bitwise result of OSC1 AND OSC2.|
|ring||OUT1 is OSC1 ring modulated (or multiplied) by OSC2.|
|min||OUT1 is equal to whichever OSC has a lower value.|
|pong||OUT1 is OSC1 if it is positive, otherwise OSC2 if it is negative, otherwise 0.|
|inlv||OUT1 is the result of interleaving the bits of OSC1 and OSC2's values. First bit from OSC1, then a bit from OSC2, ...|
|and||OUT1 is the bitwise result of OSC1 AND OSC2.|
|xor||OUT1 is the bitwise result of OSC1 XOR OSC2.|
|gLcH||OUT1 is the result of a complex bitwise algorithm combining OSC1 and OSC2.|
Both oscillators can be synced:
When INT SYNC is flashing, the internal sync oscillator is half the frequency as OSC1.
Press SYNC/PULSE/STEP and turn data encoder to select sync modes for each oscillator.
|Hard||Oscillator phase is reset to zero when sync occurs.|
|Soft||Oscillator phase is reset to zero if it is within the first 1/4 of it's cycle when sync occurs.|
|Rev||The oscillator direction is reversed when a sync event occurs.|
|Hold||Oscillator switches between holding a steady value, and running normally, on each sync event.|
|1shot||Oscillator runs for one cycle of the waveform on each sync event. Useful in LFO mode to act as a complex envelope.|
|Bump||Oscillator's phase is incremented by 1/4 a wavecycle on each sync event.|
|2=1 Sync||Same as Hard mode, but also generates additional sync events on oscillator 2 whenever oscillator 2 and 1 have equal output values.|
|1=2 Sync||Same as Hard mode, but also generates additional sync events on oscillator 1 whenever oscillator 1 and 2 have equal output values.|
|Off||Sync events have no effect on the oscillator.|
Pulse mode controls the PULSE output signal functionality, which outputs either a 0v or 5v value.
Press SYNC/PULSE twice and rotate data encoder to modify PULSE function.
|+o1||high when either oscillator 1 is positive, otherwise 0.|
|+o2||high when either oscillator 2 is positive, otherwise 0.|

|AND||high when oscillator 1 and 2 is positive.|
|XOR||high when one of oscillator 1, or 2, but not both, are positive.|

|sq2||square wave with frequency equal to oscillator 2.|
|pmw1||pulse width waveform with frequency equal to oscillator 1, and variable width controlled by SHAPE 1.|

|RND2||random value, updated once at the start of every cycle of oscillator 2.|
|MOD A Destinations|
MOD A modulation input is high speed (96khz) and AC-coupled. It is normalized to OUT 1, so even with nothing patched the MOD A attenuator is an important control for the output of the patch.
To Change MOD A modulation destination, press MOD A / MORPH and turn the data encoder.
|Phase2||MOD A modulates the phase of oscillator 2.|
|Combo 2||MOD A's signal is sent into the COMBO MODE oscillator combiner in place of oscillator 2.|
|Shaper 2||MOD A is used to address the wavetable for oscillator 2. PITCH 2 and RATIO have no effect, and instead the MOD A signal is converted to an address in oscillator 2's waveform. For example, a rising sawtooth sent to MOD A would emit oscillator 2's waveform at the same rate as the input sawtooth.|
|Voc MOD||MOD A is used as the modulation signal for the 64-band vocoder. The output of the oscillator COMBO is used as the carrier signal.|
|Phase 1||MOD A modulates the phase of oscillator 1.|
|Combo 1||MOD A's signal is sent into the COMBO MODE oscillator combiner in place of oscillator 1.|
|Shaper 1||MOD A is used to address the wavetable for oscillator 1. In Chord Mode only the first oscillator is affected.|
|Voc CARR||MOD A is used as the carrier signal for the 64-band vocoder.|
|Sync 2||MOD A is used as the sync input for oscillator 2, allowing oscillators 1 and 2 to be syncronized to different signals.|
|PrstStep||MOD A is used as a trigger to step in PRESET STEP mode. This allows the SYNC input to be used for sync signals or preset stepping.|
When CHORD MODE is enabled, oscillator 1 emits 8 waveforms with the same shape, but different frequencies.
Press CHORD MODE and rotate data encoder to pick the chord shape (see table below).
Chord voices can also be detuned and overdriven via CHORD DETUNE and CHORD DRIVE functions which are active when CHORD MODE is active.
